The thermodynamic data for CHF Cl contained in this paper are a basis for formulations 2 of the thermodynamic behavior of this special substance. It will also contribute to the improvement of formulations for new substances.
The massic heat capacity cp = (1h/1T)p of 1,2,2,2-tetrafluoroethane (refrigerant R134a) was measured at 18 temperatures from 253 K to 523 K at pressures between 40 kPa and 30 MPa. The Joule-Thomson coefficient mJT = (1T/1p)h of this substance was measured at six temperatures from 333 K to 423 K at p
